Trump: London mayor has done a "terrible job"

Trump said Khan had “done a very bad job on terrorism” and a “terrible job in London.”

“I think he has done a bad job on crime, if you look, all of the horrible things going on there, with all of the crime that is being brought in,” Trump told The Sun.

Trump also took issue with the fact that he felt Khan had not been respectful to him.

He continued: “I think he has not been hospitable to a government that is very important. Now he might not like the current President, but I represent the United States. I also represent a lot of people in Europe because a lot of people from Europe are in the United States.”

Some background: Long before Trump became president, he was trading barbs with Khan. After Khan was elected as London's first Muslim mayor in 2016, he frequently criticized Trump and described his views of Islam as ignorant. Trump called for an IQ test between him and the mayor to determine who's smarter.

He continued: "I have a lot of respect for Boris. He obviously likes me, and says very good things about me. I was very saddened to see he was leaving government and I hope he goes back in at some point. I think he is a great representative for your country.”

Trump refused to be drawn into saying if Johnson should replace Theresa May as prime minister.

“I am not pitting one against the other," he told The Sun. "I am just saying I think he would be a great Prime Minister. I think he’s got what it takes.”

President Donald Trump touched down in the United Kingdom Thursday and spoke with a major British tabloid where he differed with British Prime Minister Theresa May on her approach to Brexit.

"I told her how to do it. That will be up to her to say. But I told her how to do it. She wanted to go a different route," Trump said, according to audio of an interview posted by The Sun.

Trump said May "didn't listen" to his views on how she should negotiate the UK's exit from the European Union, but said that was "fine."

"She should negotiate the best way she knows how, but it's too bad what's going on," Trump said.

Trump's comments in the interview are an extraordinary criticism of a foreign leader during a trip to that leader's country. Trump was greeted by May in a ceremony full of pomp and circumstance Thursday evening just hours before the interview was released.

British Prime Minister Theresa May spoke at a dinner with President Trump and key business leaders Thursday night. Here are a few key lines from the address:

On the US and UK's friendship: "Time and again, the common threads that hold us together — our shared history, our shared values, our shared language and culture — conspire to inspire mutual respect, and to make the United States and the United Kingdom not just the closest of allies, but the dearest of friends."

On confronting Russia: "As was the case in Churchill’s time, and in many years before and since, it’s there in our joint efforts to protect our shared security — whether through targeting Daesh [ISIS] terrorists or standing up to Russian aggression."

On co-investment: "As the largest investors in each other’s economies, with over a trillion dollars of investments between us, the US and UK do an incredible amount of business together. Thousands of US companies have a home in the UK, providing jobs for over million people here. And the strength and breadth of Britain’s contribution to the US economy cannot be understated. The UK is the largest investor in the US, providing nearly a fifth of all foreign investment in your country."

On British companies that employ Americans: "There are thousands of British employers with a long-term presence in the US, providing well-paid work and driving economic growth in every state ... Tomorrow morning, around 24,000 men and women in Michigan will get up and go to work for a UK-owned company ... Another 40,000 will do the same in Ohio. Sixty thousand in Pennsylvania. In Texas, British employers provide work for an incredible 100,000 people. Altogether, from Maine to Alaska, more than a million Americans work for British companies."

On leaving the EU: "Now, as we prepare to leave the European Union, we have an unprecedented opportunity to do more. It’s an opportunity to reach a free trade agreement that creates jobs and growth here in the UK and right across the United States ... It’s also an opportunity to tear down the bureaucratic barriers that frustrate business leaders on both sides of the Atlantic."
